Intermediate units
On the parallel bus PCB “P34 – Bus Interface IM0048” of the intermediate units of the
parallel system the Jumpers JP1, JP2, JP3 and JP4 must be removed.
On the parallel bus PCB “P34 – Bus Interface IM0048” of the intermediate units of the
parallel system the Jumpers JP1, JP2, JP3 and JP4 must be removed.
In a parallel system composed of 2 or more units, only the first and last units
(having 1 input JA and JB free) have the Jumper JP1, JP2, JP3 and JP4 inserted on
parallel bus PCB “P34 – Bus Interface IM0048” (see Fig. 3.10-2).
(having 1 input JA and JB free) have the Jumper JP1, JP2, JP3 and JP4 inserted on
